xte -d

Published 2023 March 11, 14:23

There is an undocumented xte flag: xte -d X, where X value above 2 will throw additional debug information. My use for it was to find a proper keycode for X86* keys.

Another way to search for keycodes is here:

cat /usr/include/X11/XF86keysym.h

Part of the output:
